My ongoing experiences with Ubuntu, and later Mythbuntu, as a media center with MythTV. I'm also using the system for a virtual machine server, a mediawiki server and a general all around home infrastructure base.

Running MythWeb remotely

DO NOT FOLLOW THESE DIRECTIONS: They've messed with my MythTV install, causing it to become unstable and forget all its recording scheduling information.
I strongly suspect it has to do with the database tweaking I did at the end, but I'm not going to try and fix it. I'm just going to run MythWeb locally, probably on a fest mythbuntu install.

This describes my installation of MythWeb on a server ( that was separate from the system running my MythTV front end, back end and mysql database (

First, on the mythtv system, configure MySQL to accept remote connections:

# grep bind /etc/mysql/my.cnf
bind-address =
# /etc/init.d/mysql restart
* Stopping MySQL database server mysqld [ OK ]
* Starting MySQL database server mysqld [ OK ]
* Checking for corrupt, not cleanly closed and upgrade needing tables.

Now create a mythweb user in the mysql database. Replace "XXXXXXXX" here with an actual password you'll use again later. (I think you could get away with skipping this step and then using the mythtv user later. I'm also not sure you need to "grant all" permissions.)

# mysql --user=root -p
Enter password:
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 163
Server version: 5.0.51a-3ubuntu5.2 (Ubuntu)

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.

mysql> grant all privileges on mythconverg.* to mythweb@ identified by 'XXXXXXXX';
Query OK, 0 rows affected (0.06 sec)
mysql> select host,user from user;
| host | user |
| | mythweb |
| casey | root |
| localhost | debian-sys-maint |
| localhost | mythtv |
| localhost | root |
5 rows in set (0.00 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.04 sec)

Mythweb uses the MasterServerIP value from the settings table to find the backend. In my case this was set to, which was fine if Mythweb is on the same system, but breaks things if they are are different systems. So change that to tell mythweb where to find the mythtv back end:

mysql> update settings set data='' where value='MasterServerIP';
Query OK, 1 row affected (0.02 sec)
Rows matched: 1 Changed: 1 Warnings: 0

mysql> select data from settings where value='MasterServerIP';
| data |
| |
1 row in set (0.00 sec

Ok, now on web server system install mythweb:

# apt-get install mythweb

And tell mythweb where to find the mysql database. Replace 'XXXXXXXX' here with the password for the mythweb user you created in the mysql database previously. (If you skipping creating the mythweb user earlier, this is where you would put in your mysql mythtv login and password instead.)

# cd /etc/apache2/sites-available/
# vi mythweb.conf
# grep db_ mythweb.conf
setenv db_server ""
setenv db_name "mythconverg"
setenv db_login "mythweb"
setenv db_password "XXXXXXXX"
# apache2ctl restart

And things should be working. Don't forget to require authentication.
